摘要
通过建立Y型圆钢管节点有限元模型,对Y型圆钢管相贯节点转动刚度进行单参数分析,同时对整个节点转动刚度进行回归分析,得出Y型圆钢管转动刚度的计算公式。
Through the establishment of the finite element model for Y-circular steel tube＇s joints,the single parameter analysis is made for the rotational stiffness of the Y-circular steel tube＇s tubular joints,while the regression analysis is made for the rotational stiffness of its entire joint,then,calculation formula is obtained for this Y-circular steel tube＇s rotational stiffness.
